SUMMARY

t l

MONTH: April 1993 i

f Catawba Unit 2 began the month of April in end-of-cycle 5 refueling outage. The unit was placed on-line on 4/1 at 1534, for a total duration of 61.67 days. The unit was held at 18% power from 1730 to 2301 in preparation for the main turbine overspeed trip test. The turbine was tripped off4ine at 2301 and was placed i

back on-line on 4/2 at 0100. During power escalation, the unit held at 20% power from 0405 to 0530 for l

flux mapping and at 30% power from 1205 to 4/3 at 1238 for flux mapping. The unit held at 56% power from 4/3 at 2200 to 4/4 at 0315 to place a second feedwater pump in service. The unit was held at 75%

power from 1300 to 2055 for flux mapping. The unit held at 80% power from 2308 to 4/5 at 0220 when the

'C' cold leg accumulator was inoperable due to boron concentration being too high. The unit reached 100%

[

power on 4/5 at 1320. The unit operated at or near 100% full power for the remainder of the month.
